Overview of this book

Data scientists, when presented with a myriad of data, can often lose sight of how to present geospatial analyses in a meaningful way so that it makes sense to everyone. Using Python to visualize data helps stakeholders in less technical roles to understand the problem and seek solutions. The goal of this book is to help data scientists and GIS professionals learn and implement geospatial data science workflows using Python. Throughout this book, you’ll uncover numerous geospatial Python libraries with which you can develop end-to-end spatial data science workflows. You’ll learn how to read, process, and manipulate spatial data effectively. With data in hand, you’ll move on to crafting spatial data visualizations to better understand and tell the story of your data through static and dynamic mapping applications. As you progress through the book, you’ll find yourself developing geospatial AI and ML models focused on clustering, regression, and optimization. The use cases can be leveraged as building blocks for more advanced work in a variety of industries. By the end of the book, you’ll be able to tackle random data, find meaningful correlations, and make geospatial data models.

Hypothesis Testing and Spatial Randomness

In Chapter 5, Exploratory Data Visualization, you started to understand the first step of exploratory spatial data analysis (ESDA), which focused on data visualization through the creation of maps derived from the New York City Airbnb dataset. During your work, you noticed that the prices of Airbnb rentals are heavily skewed across New York’s geography, with what appeared to be groups of census tracts with higher and lower values in different parts of the city. For reference, take a look at Figure 6.1, which represents New York City Airbnb prices as a choropleth map. Areas highlighted by the red circle are groupings of higher values, while areas highlighted by the blue circle are groupings of lower values:

This chapter focuses on the second critical part of ESDA, which is testing for spatial structure present within data. Testing for spatial structure is important because...
